Subject: BCM270X_DT: Add reference to audio_pins to CM dtb
X-Git-Tag: archive/raspbian/4.9.82-1+deb9u3+rpi1_jessie~5^2~354
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=abc0e10ea4e72ee1eedf80c871b38835cdadc2da;p=linux-4.9.git

BCM270X_DT: Add reference to audio_pins to CM dtb

The CM1 dtb contains an empty audio_pins node, but no reference to it.
Adding the usual pinctrl reference from the audio node enables the
audremap overlay (and others) to easily turn on audio.
